Abstract: The paper endeavors to describe the patterns and trends of elderly population in the Philippines with specific comparison to those occurring in Mindanao and in Region XI. The distribution of elderly population by urban-rural classification and its other demographic characteristics in Region XI is likewise explored. Data for this paper were derived mainly from the Philippine census count for the years 2000, 2007, and 2010. Census data for the Philippines indicate an increasing percentage of population aged 60 years and over relative to household population, a trend which is also observed in smaller geographic groupings such as Mindanao and Region XI. Further, census data indicate a growing feminization of the elderly population and that the proportion of elderly population is increasingly found in urban areas. The growing proportion of elderly population in the country requires a number of social, institutional, and political adjustments particularly in the aspect of healthcare and social security benefits.
